Title: Optical waveguide demultiplexer
Inventor: SHIRASAKI MASATAKA
IPC: G02B6/34
Filed: 1986-02-07
Abstract: PURPOSE:To execute accurately the positional adjustment of an optical system arranging at least two single mode fibers near both the ends of a fiber array and coupling the two single mode fibers each other. CONSTITUTION:Light beams inputted from one single mode fiber SM in the fiber array 1 are turned to parallel beams through a lens 3 and reflected by a diffraction grating 2. The beams separated in respective wavelengths by the reflection based upon the diffraction grating 2 are passed again through the lens 3, concentrated into plural multimode fibers MM formed in respective wavelengths and outputted. To adjust the positions of the fiber array 1, the diffraction grating 2 and the lens 3 in the demultiplexer, a system for inputting a light beam from one of two single mode fibers SM arranged on both the ends and outputting them from the other is used. Since the core of each single mode fiber is thin, the position of the optical system can be accurately adjusted.

Title: Build-up welding method
Inventor: SHIMADA WATARU
IPC: B23K9/04
Filed: 1979-03-05
Abstract: PURPOSE: To reduce the spreading diameter of opposite-polarity arc and prevent welding defects such as lack of penetration by changing the mixing ratio of shielding gas at the joints of beads.  
     CONSTITUTION: When the center position of an arc 2 reaches the end part C of a weld bead 3 from the point A on base metal 5, shielding gas 4 is changed from "X" 104 to "Y" 103. Then, the relation of the mixing ratio of CO 2  or O 2  in the shielding gas 4 becomes X<Y and the spreading diameter D of the arc 2 becomes small. As a result of this, the energy density of the arc 2 increases and the end part C of the weld bead 3 is concentrically heated and melted.

Filed: 1995-02-14
Abstract: PURPOSE: To output the image signal having an exact have even if the location of an exit pupil is changed by correcing the ratio of the stimulation valve of a color according to the location of the exit pupil. CONSTITUTION: The incident light from an optical means 11 forms an optical image on an image pickup means 12 via an on-chip microlens 12a The image pickup means 12 performs a photoelectric conversion for the optical image and outputs the image signal. The ratio of the stimulation value of the color of this image signal is changed according to the location of the exit pupil of the optical means 11 due to the cause such as the color aberration on the axis of the lens 12a, etc. A color correction means 13 fetches the location of the exit pupil of the optical means 11 and corrects the ratio of the stimulation value of the color of the image signal for which the photoelectric conversion is performed by the image pickup means 12 by the correction amount which is preliminarily fixed corresponding to this location of the exit pupil.  Therefore, the fluctuation of the stimulation value can be canceled by the location of the exit pupil and an image signal whose hue is exact is outputted.
